i 'o 'aZZ whom it may concern: I Be it known that I, JAMES E. RIELLY, a citizen of the United States, residing at'NeW of Essex and State of New Jersey, have invented certain new and useful Improvements in Spring-Wheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the to the accompanying drawings, and to letters 'of reference marked thereon,- which form a part of this specification.

that embodies a rim portion surroun 'eorrugated so as to relates to a sprin wheel ed by a fellyof the wheel, the space by a corrugated one piece rim carrying a tire on its pe- This invention space from the being occupied spring, and the riphery.

The invention further provides for a sprm so arranged between the folly and the 'r1rn, t h

at it will be adapted for the transmispower from the felly to the rim, or V106 versa. The spring is not secured to either one of the members, and'is free to contract and expand throughout its full length. The invention is illustrated in the accompanying drawings, in which igure 1 is an elevation of a wheel with one of the annular side plates cut away to show the spr' and Fig. 2 is a view half in elevation and alf in section.

p In the drawings is shown a hub portion 10 which can be of any construction, and is. pro- Vided with the spokes 11, and on the end of the spokes is affixeda felly 12. This felly is preferably bound with a steel or similar band i 13 arranged to take up the Wear of a spring.

sion -,of

p 46 Considerably larger than the felly and surrounding 1t, is a rim 14, and between the rim andthe felly is arranged a spring 15 which 1s bringits convolutions 1n ,'contact with the .felly and then with the rim,

- ends 16 are disengaged so as and so on around the wheel, and this spring is preferably made of one piece, and the two to allow the expansion-and contraction of the spring due to the variations of load and speed. The

I spring 15 has its corrugations arranged alternately in the recess 13, and in the recess 14*, these recesses being in the outer edge of the band 13 of the felly, and the inner edge of the rim portion la, respectively. It will be seen from this 'arrangement,that when power is applied to the axle to drive the wheel, or the power applied to the hub, that the-spring, by reason of itscorrugations being in the recesses or depressions, will bind and act to transmit rotation of one member to cause rotation of the other. At the same time these recesses do not interfere in any way with the resiliency of the sprmg,and do not prevent an easy riding of the wheel. 1

A plate 17, on each side of the wheel, is secured to the rim by the bolts 18 and extends across the space in which the spring is placed, and partially over the felly to keep out dust and dirt, and-at the same time to give the wheel the proper finish. Each plate 17 has an inturned portion 19 which grasps a tire20 arranged around the rim, and thus serves to secure this tire.

This wheel is cheap, and the spring, if broken, can be easily replaced, and at' the same time there is a distribution of wear. Attention is also called to the free ends 16 of the spring which can ride one over the other when the spring is very muchcompressed, and thus the chances of breaking the spring are IninimiZed.

Having thus described my invention, what I claim is:'

A spring-wheel comprising a body-portion having a folly, a rim surrounding the felly at a distance therefrom to form a circumferential space, and an evenly corrugated fiat spring in the space and engaging the felly and the rim, the felly and rim being provided with recesses of less than a semicircle to receive the corrugation of the sprin In testimony, that I claim the foregoing, I have hereunto set my handthis twenty seventh day of November 1906.

JAMES E. RIELLY.
